The Korean Grand Prix preview

Formula 1 arrives at Yeongam for its second ever Korean Grand Prix with the drivers' title settled, but every chance of a thrilling and highly unpredictable race

Circumstances couldn't be more different heading into Korea this year compared to last. Back then Sebastian Vettel was third in a five-way fight for the Formula 1 title, whereas he now arrives at the Yeongam circuit as only the ninth back-to-back world champion in the sport's history.

But while the drivers' title has been settled, there is still much to be decided in the final four races, while a number of questions about the race itself remain unanswered following its rain-hit F1 bow in 2010.
